Named after one of the three Erinyes of Greek mythology, Megaira released their debut "Power, Lies and Death" in 2017, a concept album drawing on stories from Greek myth including the Minotaur, Icarus, and the punishing goddesses who lend the band its name. The record pairs guttural death metal vocals from Paulo Schmidt against the clean, heavy metal delivery of Annia Bertoni, layering thrash aggression with melodic power metal hooks and black metal atmosphere.

Moriquëndi was a power/progressive metal band from Mendoza founded in 1998 by Roly E. Testini (1975–2008), whose songwriting drew from J.R.R. Tolkien's mythology and his own original fantasy stories. The band's debut demo El Último Elfo Oscuro was recorded in January 2001 at Estudios ADN with Aníbal Rivero and Diego Rubio, and the lineup included drummers Marcelo Narváez, guitarists Javier Vildoza and Sebastián Narváez, bassist Gabriel Narváez, and keyboardist Nicolás Sánchez.
